IMPn'ovED oAE-'coUPLINa TO ALL 'llHCrM lIT MAY CONCERN:

l Be it known that I, ABnAM PERRIN, of Cleveland, Stat'e of Ohio, have invented'a new Car-Coupling; and I do hereby declare that the following is a full, clear, and exact description thereof', referencebeing had to the accompanying drawings, and to thevletters of reference marked thereon.

v The nature of my inventionjconssts in constructing a self-acting careoupling,which shall couple itself without assistance as the cars come together-,and remain securely coupled untilreleased by hand.

To enable others skilled in the art to make and use my invention,I will proceed to describe its construction and operation. Figure 1 is ahorizontal section. Y l

' Figure 2 is a side view.

l'igure is an end view of the coupling-bar or draw-bar.

Figure 4 is a section through the coupling-bar.

A is the frame of the eoupling, having riveted on its end the bumpers'B. C is a casting riveted inside the frame A. Its rear portiou,e, extends ,across -the frame, and cts as astop to receive the thrustvof the drawbar in coupling. The forward part is groovetl,` and opensat one side, c2 to admit the draw-bar. It also makes a-shoulder, e, which receives the pull of the draw-bar. Close to the shoulder c3. the groove just fits the drawban' At the other end, c, itaresoiutwards, to allow. s'uicent play to that end ofthe draw-bar.

The drapwbar D is formed with `au arrow-head, d, -the 'barb of which bears against the inside edge of the bumper B. This head is made wider than the opening between the bumpers, and consequently has to be'turned from its natural horizontal position-in order to enter. This is accomplished by forming the points ofthe arrowhead on :i twist, as shown in iig.Y 3, so that when theheai enters the opening 6,'the points of contact are not in the same horizontal line; andthe force applied in bucking theears together, turns the head d until it enters the opening, when theweighted lev- G- causes it to rsume once moi-edits horizontal'p'osition.

A rod bearing against a. spring would answer instead of this weighted lever, but be simply an equivalent. This twist of the drow-bur might also be given by au iuolineon the bottom of theopening b, through which the arrow-head enters. I

The partd'just behind the head d, ills the opening b., The head di, on the other end of the draw-bar, receives the pull against the shoulder o3', an'dalso the thrust against the block c, in coupling. Upon one side of this head d is a projecting pin, e, shown in iig.' 4, which fits into the groove e. When the draw-boris forced back against thestop c, there is sucient play to allow of the draw-bar being turned, as in coupling, or by the hundppplied tothe weighted lever G in uncoupling; .but as soonas the pull of the train comes upon the draw-bar, the p'inA ie enters the groove c", aud prevents the turning of .said bar; the

harder fh@ `pull of the train, thejrmer the'bar retains its position. .The pin 1i, dropped in from the top, secureiny Athc draw-bar in position.

The opening 6 in theb'unpers Ais'made high enough -to permit considerable variation in the' height of the cars, without affecting the operaticir of'this coupling. y v

One draw-bar being su'ieient for each-car, should two couplings come together without a draw-bar, it can be brought from the oppostecnd ofthe car'. t

A supplementary link, H, fig. 5, .may be carried during the change from one system of couplingtoithe anothenso as to connect aear having the oboveimprovement with'one having the common coupling. i

What I cla-iin as my invention, and desire to secure by Letters Patent, is- Theeonstructionof the draw-head A, with its `open side, and pin h, and having stops che, and c5, of the form vshowm,`n combination with the link or connecting-irons D and H, the former being provided with a head,

all, and lug 2, and weight G, all substantially as aud for the purpose setforth. Y s ABRAM PERRIN.
